We get asked this question a lot. That's why we are here to help. It's not easy to choose a 3D scanner that needs to capture different sizes, surfaces, shapes and textures. It also depends on your budget. The difference in price comes from different components such as the camera lens, projector, light source, and software complexity.
Let's outline 4 important features you need to understand to decide which model would be most suited for your project.
1. Light Source - Structured Light Or Laser?
2. Accuracy and Resolution
The accuracy gives an information about the authenticity of a 3D model to the real object. Knowing the accuracy of your scanner is very important because it determines which model is most suitable for quality inspection, reverse engineering design, medical health, or any other applications with very rigid accuracy requirements. Usually, the higher accuracy the scanner is able to generate, the more applications it could be suitable for, and of course, the higher the cost.
Remember though, not all 3D scanning projects require the highest accuracy, so consider your budget and requirements to make a decision on which model to purchase. The accuracy used in the specifications of the scanner usually refer to the accuracy of a single scan. The volumetric accuracy refers to the relationship between 3D data accuracy and object size; with EinScan Pro Series the accuracy is reduced by 0.3mm per meter. This data is based on measuring the center of sphere with marker alignment. The volumetric accuracy of EinScan HX in laser mode is 0.06 mm per meter.
With EinScan handheld 3D Scanners the Pro Series and the H series, the resolution can be changed depending on the object size to ensure the 3D scan data size is manageable.
3. Scan Speed
Scan speed is a specification that definese how long it takes to scan one given object. It especially matters when you are going to scan the human body, as people can not stay still for a long time, and it also helps to improve the work efficiency when you are 3D scanning large objects like cars, buildings, etc. Scan speed can be defined by the number of points collected per second, frames per second, or how many seconds it takes to do a single scan. The more points or frames collected per second, the faster the scan speed.
4. Desktop or Handheld
Desktop 3D scanners are provides higher accuracy and enables automation of the whole 3D scan process. The EinScan Pro series handheld 3D scanners can be turned into a desktop/fixed 3D scanners with the Industrial Kit. For 3D scanning larger objects (like humans or cars), using the handheld 3D scanner is the only solution.
So which model shall I buy?
Here is a comparison at a glance.
In reality all of the above models have similar accuracies.
EinScan Pro HD and EinScan Pro 2X 2020 both have the same accuracy of 0.045mm in Handheld HD mode, while it is 0.05mm for EinScan H in body and standard mode, and 0.04mm for EinScan HX in laser mode. So accuracy might not be a critical parameter for you to choose a proper device among EinScan series. If high accuracy is a top priority on your agenda, EinScan HX is the best choice among all EinScan scanners.
EinScan Pro Series (2X 2020 & HD) achieves a higher resolution compared to EinScan H series. Resolution captured by EinScan Pro 2X 2020 is marginally higher than the Pro HD due to the single scan range being smaller.
The EinScan H series have a different projecting pattern to the Pro Series thus the resolution is lower. But remember, the EinScan HX can achieve a higher accuracy vs. the Pro Series.
Scan Speed Comparison
To compare the speed of scanners, two facts need to be considered: single scan range and the points captured per second.
For points captured per second, in Handheld Rapid mode, all scanners of the EinScan Pro Series come with the same speed of 1,500,000 points/s. However as the EinScan Pro HD has a larger single scan range, it can scan large objects at a faster speed. EinScan H (standard scan&body scan) and EinScan-HX (rapid scan) come with the same scan speed in terms of points captured per second and scan range, which are all faster than Pro series. In the face scan mode of EinScan-H, the maximum scan range could reach 780mmx 900mm enabling a fast scan.
